Agricultural-waste granular fuel

Abstract

The invention discloses an agricultural-waste granular fuel. The agricultural-waste granular fuel is characterized by containing the following substances in parts by weight: 10-15 parts of poplar wood sawdust, 10-15 parts of coconut tree wood sawdust, 10-15 parts of elm sawdust, 16-29 parts of hemp straw powder, 33-46 parts of sunflower stalk powder, 40-56 parts of rice hull powder, 15-30 parts of soybean straws, 12-20 parts of goose feces, 10-15 parts of pig manure, 9-16 parts of Juniperus chinensis wood sawdust, 1-3 parts of white bark pine wood sawdust, 11-18 parts of grevillea robusta limb and 14-30 parts of willow tree limb. According to the agricultural-waste granular fuel, various crop straws and tree limbs are combined, the source of raw materials is relatively extensive, and waste biomass is fully utilized, so that the aims of energy saving and environmental protection are achieved; by adding the coal powder, the content of charcoal in the granular fuel is effectively increased, the burning time is prolonged, and the calorific value of the biomass granular fuel is greatly increased.

Description

technical field [0001] The invention relates to an agricultural waste granular fuel. Background technique [0002] At present, the commonly used fuels are mostly coal, oil, and gas, and these resources are non-renewable. Rice husks and sawdust powder from crops have been used as fuel in rural areas for a long time. The traditional way is to burn directly with kangs and stoves. This method has low energy conversion efficiency, high fuel consumption, limited functions, and cannot sustain stable combustion by itself. Heating, low combustion intensity, weak firepower, time-consuming and labor-intensive. [0003] Pellet fuel made from waste and renewable biomass resources is not only energy-saving and environmentally friendly, but also has high calorific value and little environmental pollution after burning. At present, the traditional biomass dense pellet fuel processing industry generally has the problems of low single raw material processing output and low molding rate in t...

Problems solved by technology

At present, the traditional biomass dense molding pellet fuel processing industry generally has the problems of low single raw material processing output and low molding rate in terms of raw material ratio

Because a single raw material requires too much raw material for production, and each single raw material will have some problems in the molding process, such as rice husk: too little fiber is not easy to shape; sawdust powder: poor adhesion and difficult to press molding
